Subject: array() ignores illegal non-list dimnames
Is there a reason that array() silently ignores dimnames that are not
a list but matrix() gives an error?
> str(matrix(11:14, 2, 2, dimnames=c("Rows","Cols")))
Error in matrix(11:14, 2, 2, dimnames = c("Rows", "Cols")) :
'dimnames' must be a list
> str(array(11:14, dim=c(2, 2), dimnames=c("Rows","Cols")))
int [1:2, 1:2] 11 12 13 14
I noticed this in lhs:::geneticLHS, which has the line
J <- array(NA, dim = c(n, k, pop), dimnames = c("points",
"variables", "hypercubes"))
where the non-list dimnames has no effect, and no warning or error.
